Abstract

The invention provides time synchronization method and device, and solves the problem that time synchronization in the prior art has defects. The method applied to a centralized control unit comprises that correspondence between the synchronization domain code and synchronization domain data is established in each time synchronization domain, the synchronization domain codes of different time synchronization domains are different, and the synchronization domain data comprises the switching relation among different time synchronization states and / or output parameters corresponding to the time synchronization states in the time synchronization state; and the synchronization domain data, which comprises first synchronization domain data corresponding to the first synchronization domain code at least, is sent to a first time synchronization node, so that the first time synchronization node implements time synchronization according to the first synchronization domain data, and the first synchronization domain code is the synchronization domain code of the first time synchronization domain to which the first time synchronization node belongs. The method and device can solve the problems in intercommunication, and realizes network multiplexing.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for realizing time synchronization. Background technique [0002] Applications in many fields require precise time synchronization. For example, in the field of mobile communications, various communication systems require time synchronization between air interfaces of base stations to work properly, including Time Division Synchronous Code Division Multiple Access TD-SCDMA, Time Division Long Term Evolution TD-LTE, code Multiple Access CDMA2000, Long Term Evolution LTE-A, Multimedia Broadcast / Multicast Service MBMS, etc. In order to achieve time synchronization, it is generally necessary to install a satellite timing receiver such as the Global Positioning System (GPS) for each user end that needs to be synchronized. This method requires high installation costs and maintenance. Another method is to set up a time synchronization network and transmit time synchronizat...
